1 Claim. (Cl. 16--137) This invention relates to door stops and moreparticularly to a door stop which is adapted to be detachably associatedwith the usual door hinge so as to be conveniently disposed away fromthe iloor in a position to stand between the door and the door frame orwall when the door is in open position. As illustrated, it is similar tothe closer shown in my Patent No. 2,638,620, granted May 19, 1953.

In the manufacture of a door stop of this 4type it is desirable that itbe economically made so that it may sell for a relatively low price andat the same time be easily installed so as not to require an expertworkman for its installation. Also, it is desirable that it beadjustable so that it may stop the door in any desired open positionwithin limits. As shown, the present stop may be adjusted to hold thedoor at a position substantially 135 degrees from its closed position orat nearly 180 degrees from its closed position when the door opens backagainst a wall substantially in the plane of the door itself when thelatter is closed.

Also as illustrated, the door stop comprises a structure of simple formwhich may readily be mounted upon the hinge pin of the usual butt hingeof a door and consists of a body portion extending outwardly from thepivot pin which at its free end carries rubber bumpers to engage againstthe door and door frame respectively.

One object of the invention is to provide an improved form of door stophaving means whereby it may be mounted upon the hinge pin upon which thedoor swings so as to stand between the door frame and the door when thelatter is in open position and limit the swinging of the door.

Another object of the invention is to provide a door stop of thecharacter described which is provided with aligned rubber bumpersadapted to engage the door and casing respectively, the bumpers beingadjustable so that the opening of the door may be limited to a desiredangular position.

A further object of the invention is to provide an improved door stop ofthe character described which will be relatively inexpensive tomanufacture, simple in construction and readily installed by anyone,thus not requiring the services of a skilled workman.

To these and other ends the invention consists in the novel features andcombinations of parts to be hereinafter described and claimed.

In the accompanying drawing:

Fig. l is a sectional view of a portion of a door having my improveddoor stop applied to the hinge thereof, and the door being shown inclosed position;

Fig. 2 is an enlarged ysectional view of the end portion of the doorstop;

Fig. 3 is a View similar to Fig. 1 showing the door in open position;and

Fig. 4 is a view similar'to Fig. 3 showing one of the adjustments ofwhich the device is capable.

To illustrate a preferred embodiment of my invention, l have indicated aportion of a door casing at 10, the

nited States Patent O ICC casing being provided with a facing member 11,and to the casing is hinged a door, the rear portion of which is shownin cross section at 12. The door 12 is hinged to the casing 10 by theusual butt hinge 13, the leaves lof which are pivotally joined togetherby the hinge pin 14 in the usual manner.

The door stop comprises an arm or body portion 16 having at one end anopening or eye 17 to receive the hinge pin 14 so that the stop may bemounted upon the door hinge. It will be noted that the arm or bodyportion 16 is not radially disposedwith respect to the opening 17 but isoffset from the center of the opening so that the outer edge of the arm18 (lower edge as shown in Fig. 1) is substantially tangent to the edgeof the opening. t e

As shown more particularly in Fig. 2, the free end of the arm 16 isprovided with a `stud 20, this stud being provided with a threadedopening 21.

In each end of this opening is adju-stably received a threaded stem 22,the stem carrying at its free end a stud 23 having an enlarged head 24over which may be frictionally telescoped a rubber bumper or cap 25.

The bumpers 25 are of substantially cup-shaped form and are made ofresilient material such as rubber, this material being of such a naturethat the bumpers may be stretched over the enlarged heads 24 of thestuds 23 and be frictionally held in position by engagement of the freeskirt portions of the bumpers below the enlarged heads of the studs. Itmay also be noted that each of the bumpers is adjustable with respect toits distance from the stud 20 by its threaded engagement with this stud.

In order to hold each of the stems 22 in any adjusted position to whichit may be turned, lock nuts 26 are provided and after the bumpers havebeen properly positioned, these lock nuts will be turned up against thestud 20 or the outer tlat face of the arm 16 as the case may be to lockthe stems 22 in position.

The operation of the device is shown in Figs. l and 3. In Fig. l thedoor is shown in closed position, and the member 16 may stand in theposition shown with one of the bumpers 25 in engagement with the face ofthe door. When the door is opened, as shown in Fig. 3, the stop will beturned with the door until one of the bumpers lies against the faceplate 11 and the other against the face of the door, as shown in Fig. 3.This will be the limit of the open position of the door, and it will bestopped in this position so that it cannot swing back and damage thecasing. The bumpers 25 may be adjusted by means of their threadedconnection with the stud 20 so as to hold the door open at an angle ofsubstantially degrees from the position shown in Fig. l or even at alesser angle if desired. It may, of course, be adjusted to permit thedoor to open to a greater extent.

In order to enable a further adjustment of the open position of thedoor, I have provided the stud 2d of such a shape that one of thebumpers may be placed upon it if desired. For instance, if it is desiredto open the door to a greater extent than is permitted by the structureas shown in Figs. 1 to 3, 4one of the stems 22 the upper, as shown inFig. 2) may be entirely removed from the stud 20. The rubber bumper 25may then be removed from the stud 23 and slipped over the stud 20, asshown in Fig. 4 of the drawing. For this purpose the stud 20 is providedwith an enlarged head 29 and a reduced annular lower portion 30 just asare the studs 23 so that the rubber bumper 2S may be frictionallyengaged with the stud and securely held in place.

With this arrangement, as shown in Fig. 4, the distance between theouter faces of the bumpers 25 is much less than is the case with thearrangement shown in Figs. l to 3, and hence the door will be allowed toopen to a greater extent. It will, of course, be understood that theremai11- ff f j 2,813,293

ing stern 22 may be adjusted within the opening Z1 of the stud 20 to agreater eXtent than is shown in Fig. 4 so as to permit the door to opento a posittion nearly lSO degrees from its closed position. Thethickness of the facing member 11 and its position with respect to thehinge pin 14 will, of course, determine to some extent the extreme openposition to which the door may be limited.

It Will be obvious from the above description that I have provided avery simple and inexpensive door stop which is capable of ya Wide rangeof adjustment to limit the -opening of the door to a desired position.Moreover, the device is made of relatively few parts and may be readilyinstalled by the average householder. It will also be obvious that byproviding the stud 2t) of the same shape as the studs 23, one of thebumpers 25 may be mounted directly upon the stud 20, thus lessening thedistance between the bumpers 25 and rendering possible a still furtheradjustment of the device.

While I have shown and described a preferred ernbodin ment of myinvention, it will be understood that it is not to be limited to all ofthe details shown, but is capable of modification and variation Withinthe spirit of the in vention and within the scope of the claim.

What I claim is:

A door stop comprising an arm having an opening at one end thereof toreceive a hinge pin whereby it may be attached to a door hinge, said armbeing offset laterally from the axis of said opening, the other end ofsaid arm being provided with an integrally formed stud having a threadedopening therethrough, a threaded stem adjustably received in each end ofsaid opening for adjustment in a direction substantially transverse tosaid arm, a stud carried by the free end of each of said stems, and `acupshaped bumper member ip frictional gripping engagement with each ofsaid last-named studs to be removably mounted thereon, and at least oneof said last-named studs being of an exterior shape substantiallyidentical With that of said first stud whereby one of said bumpermembers may be removably mounted on the latter.
